Abstract
A method for the detection of leaks in a heat exchanger having discrete flow paths for working fluid and heat exchange fluid, respectively, the method comprises introduction of a detection fluid within one of said flow paths and allowing air to flow through the other of said flow paths causing the detection fluid to pass in different directions in said one flow path, and detecting any detection fluid which has leaked from one flow path to said other flow path.
